GPC (GlyceroPhosphoCholine) and PS (PhosphatidylSerine) are phospholipid nutrients intensively researched for their benefits to diverse human brain functions. These nutrients naturally complement each other: GPC reaches very high concentrations inside cells; PS is a building block for cell membranes that generate the brain's energy and electricity. Numerous double-blind trials catalog the benefits of GPC and PS for people of all ages.
